Title: Megavoltage computed tomography during radiotherapy
Inventor: MACKIE THOMAS R
IPC: A61B6/03
Filed: 2000-03-29
Granted: 2004-08-24
Abstract: Reduced dose megavoltage CT images are obtained using low flux data resulting from leakage through modulating shutters and/or collected by other means and augmented by incomplete high flux data collected during radiation therapy. The ability to construct tomographic projection sets from significantly varying flux rate data is provided by the use of air scans windowed to account for variations in mechanical leaf movement. These methods are also provide a means of imaging the patient entirely during radiation therapy treatments without any additional scan time.

Granted: 2007-07-31
Abstract: A tongs monitor for monitoring the tightening of tubing, casings, and sucker rods of a well is selectively operable in a learning mode and a monitoring mode. A target tightness value is determined during the learning mode. Subsequent tightness values are then compared to the target value. For example, a first connection is tightened in a conventional manner, while its tightness is monitored during the learning mode. If the tightening process went well, then an operator pushes a button that tells the monitor to remember how tight the first connection was tightened. The tightness value of that first joint then becomes the target tightness value for any subsequent joints. As additional joints are tightened, their tightness are monitored and compared to the first one to ensure that all the joints are as good as the first one within an allowable tolerance.

Abstract: A method and apparatus are provided for automatically sensing the presence (or absence) of spot dispensers such as pins in various possible mounting locations in the printhead of a microarray spotting instrument. Pin-location data obtained by the method and apparatus is provided to the computer controller of the instrument, which uses the data to control the motion of the printhead during operation of the instrument. A pin detection apparatus includes one or more sensor elements that automatically sense possible pin locations in the printhead for the presence of pins. The sensor elements are preferably arranged in an array corresponding to the array of pin locations in the printhead so that pin detection at each pin location can be performed simultaneously. Various types of sensor elements can be used to locate pins in a printhead. For example, sensors can be used that are remote from or attached to a printhead. Pin sensors can be used that sense pin locations from various positions relative to the printhead including above or below the printhead.  Also, pin sensing can be by contact or non-contact mechanisms. The method and apparatus allow pin positions in a printhead to be quickly and accurately determined, and without significant risk of damaging the pins, which are fragile.
